Stephen Hench Trial Attorney, Litigation & Enforcement National Highway Traffic Safety Administration 1200 New Jersey Ave, SE, Room W41-227 USG 4760 Washington, DC 20590 NHTSA-2015-0055 Re: General Motors LLC’s Amended Request to Modify Certain Sufficient Supply and Launch Deadlines under Paragraph 39 of the Third Amendment to the Coordinated Remedy Order (the “Extension Request”)

Dear Stephen:

On August 25, 2017, GM requested, pursuant to paragraph 39 of the Third Amendment to the Coordinated Remedy Order (the “ACRO”), that NHTSA modify the Sufficient Supply and Launch Deadlines for the GMT900 vehicles covered by GM’s Inconsequentiality Petitions (the “GMT900 Vehicles”). Since that filing, GM and ZF (formerly TRW), GM’s replacement inflator supplier, have made substantial progress preparing to conduct a remedy campaign, if necessary, on the GMT900 Vehicles and in assembling a substantial bank of PPI3 guanadine nitrate replacement inflators—progress detailed in the October 16, 2017, January 2, 2018, and March 28, 2018 Sufficient Supply and Remedy Launch Certification Reports (the “Supply Reports”) that GM submitted to the Agency.

Drawing on repair-rate data from other GM recalls, including recalls of Takata airbag inflators, GM recently conducted an in-depth analysis of its readiness to launch a recall campaign on the GMT900 Vehicles. Based on this analysis, GM hereby amends its August 2017 Extension Request to account for the following facts and developments:

1. Priority Group Six GMT900 Vehicles

As of June 21, 2018, GM had approximately 486,000 replacement inflators in its warehouse in Pontiac, Michigan. Totaling approximately 2.5 million GMT900 Vehicles, Priority Group Six is the largest of the priority groups covered by GM’s petitions; the other three priority groups together total only 1.6 million vehicles. Even with a substantially larger bank of replacement parts, GM’s analysis indicates that launching all 2.5 million vehicles in Priority Group Six simultaneously could rapidly deplete GM’s bank, stress GM’s dealer network, and delay the launch of subsequent priority groups.

2. GM’s January 2018 Third Inconsequentiality Petition

GM’s original August 2017 Extension Request included GMT900 Vehicles in Priority Groups Six, Seven, and Eight, then the only GMT900 Vehicles covered by one of GM’s Petitions. In January 2018, GM filed its Third Inconsequentiality Petition, which covered Priority Group Nine vehicles. Under the ACRO, these vehicles would have been scheduled to launch on June 30, 2018.

1 3. Unforeseen ZF Supply Delays

Under its contracts with GM, ZF committed to supply GM with replacement inflators in the following volumes: (i) 900,000 in 2018; (ii) 1,095,000 in 2019; and (iii) 1,525,000 in 2020. Citing supply constraints, ZF has been unable, thus far, to supply GM with replacement inflators at the contracted rate of 900,000 parts-per-year that GM paid for under its capacity reservation and supply agreements with ZF. Over the last few months, ZF has not met GM’s supply releases and informed GM that it was unable to supply more than approximately 50,000 replacement inflators per month.

GM is actively working with ZF to increase this production rate. On June 20, 2018, at GM’s insistence, ZF committed to increase production of replacement inflators, but not to the extent required to supply GM with the promised 900,000 replacement inflators in 2018. Moreover, ZF has indicated to GM that it will backload 2019 replacement inflator shipments to the end of 2019, further disrupting GM’s near-term capacity to build a bank of replacement parts and replenish that bank if a launch occurs. Although ZF’s unexpected production shortfalls have delayed GM’s progress in assembling its bank of replacement inflators, GM has still amassed a bank of approximately 486,000 replacement inflators as of June 21, 2018, and expects to have 900,000 by the end of 2018.

4. GM’s Amended Request For Relief

To facilitate an orderly launch and avoid part shortfalls, GM’s revised launch schedule, attached as Exhibit B,1 divides the 2.5 million GMT900 Vehicles in Priority Group 6 into three tranches: (i) Tranche A, containing 2007-2008 Zone A vehicles; (ii) Tranche B, containing 2009­ 2011 Zone A vehicles; and (iii) Tranche C, containing 2007-2008 Zone B vehicles. Because GM’s three Petitions remain pending, GM’s proposed launch dates are calculated from the effective date of a final order denying the Petitions (a “Final Order”).

After the Final Order, GM’s proposed launch schedule provides for a 120-day ramp-up period, which will allow GM to:

• notify the approximately 1 million owners of GMT900 Vehicles in Priority Group Six Tranche A (owner notification for each subsequent launch will commence at the start of its corresponding launch date);

• secure sufficient hazardous material transportation and logistics support to transport large volumes of replacement inflators from GM’s central warehouse in Pontiac, Michigan to GM dealers nationwide; and

1 GM’s revised launch schedule is based on GM’s current replacement inflator bank and ZF’s most recent representations regarding its capacity commitment to supply GM with replacement inflators. The launch schedule is subject to change as GM continues to build its bank of replacement inflators and work with ZF on increasing its production rate. 2
